Windwall Suggestion

Have each Champion Originating Projectile that runs into the Windwall reduce its duration. I'm not sure on the numbers precisely, and one could have attacks reduce a different # than spells, and ultimates reduce more than basic abilities. Riots main issue with giving the windwall functional HP is that it's either a noob trap to try and break, or the wall is useless and never blocks anything. Making the hits reduce the duration allows for a partial effect. This works for Azir Turret, where the Duration Timer and the HP Bar are melded, and damage speeds up the innate self-destruct.

I wouldn't recommend a literal HP bar for Windwall, mind. More something along the lines of "Basic attacks reduce duration by 0.X seconds", "Basic abilities reduce duration by 0.X seconds", and so on. It could also have a Minimum 1 second duration or some such, if we're really that worried about it immediately ineffectually popping.

This might require a tiny bar indicating to everyone how much duration is left in wind wall… but that's probably something that should already be in the game for most champion-built walls (Ex: Anivia wall, J4 wall).
